the relative impacts of different types of land use on the surface water quality are yet to be ascertained and quantified. in this paper, the influence of different types of land use on surface water quality is investigated. rain events samples from different land use in the central plateau, iran, were analyzed for major ions. statistical analyses were employed to examine the statistical relati...

We present an instrument that uses a novel technique to render topographical maps of microscopic reflecting surfaces in which depth resolution can be an order or magnitude or more better than the lateral resolution of the confocal microscope. In a confocal scanning reflected-light microscope, the illumination light coming out of the objective is a cone of light with its axis parallel to the opt...

Abstract:This methodology involves complementary square split ring resonators and a microstrip patch antenna both designed to resonate at same frquency.The proposed antenna is made by using metamaterial reflecting surface to obtain the maximum gain hight of reflecting surface is adjusted.we uses an array of squared split ring resonator (SRR) printed on a low dielectric constant material as the ...

With the capability of reconfiguring wireless electromagnetic environment, intelligent reflecting surface (IRS) becomes a new paradigm for designing future communication systems. In this paper, we consider optical IRS improving performance visible light (VLC) under multiple-input and multiple-output (MIMO) setting, where mean square error (MSE) IRS-aided MIMO VLC is minimized by jointly transce...

Millimeter wave communication is eminently suitable for high-rate wireless systems, which may be beneficially amalgamated with intelligent reflecting surfaces (IRS), while relying on beam-index modulation. Explicitly, we propose three different architectures based IRSs modulation in millimeter communication. Our schemes are capable of eliminating the detrimental line-of-sight blockage frequenci...
